Porsche 911

The 911 is a car marketed by Porsche since the sixties. Originally a two liter, larger engines have since been made available. A Porsche Carrera version is also available, and is named after the Carrera Panamericana (Pan-American Race). The 911 has competed successfully in grand tourer racing. This includes the IMSA GT Championship, American Le Mans Series, Rolex Sports Car Series, Pirelli World Challenge, and Continental Tire Sports Car Challenge. In IMSA GT the "whale tail" version was used. The original two liter was used in the Trans Am Series under two liter class. It is also used in the IMSA WeatherTech SportsCar Championship. The 911's golden anniversary was tributed at the Monterey Historic Automobile Races in a special, all-911 "Weissach Cup" race group. Even though Trans Am was supposed to be a sedan championship, the 911 was allowed due to its back seat. The 911 was designed to succeed the Porsche 356.
